mitmekomponentse süsteemi paagutamine (enamasti tardfaaspaagutamine), millega kaasneb uute keemiliste ühendite moodustumine komponentide baasil; kasutatakse pulbermaterjalide tootmisel rasksulavate ühendite (karbiidid, boriidid, nitriidid, silitsiidid jms) baasil, samuti ka nn pseudosulamite saamisel (vt paagutus), the sintering process where an exothermic reaction is initiated in a mixture of dissimilar (elemental) powders; the reaction produces a compound (carbide, boride, or other compound) and the heat from the reaction is used to simultaneously sinter the product phase (see: sintering)
